The dose-response effect in routinely delivered psychological therapies: A systematic review
The dose-response effect refers to the relationship between the dose (e.g., length, frequency) of treatment and the subsequent probability of improvement. This systematic review aimed to synthesise the literature on the dose-response effect in routine psychological therapies delivered to adult patients with mental health problems. Twenty-six studies were eligible for inclusion. Different methodological approaches have been used to examine the dose-response effect; including survival analysis, multilevel modelling and descriptive cluster analyses. Replicated and consistent support was found for a curvilinear (log-linear or cubic) relationship between treatment length and outcomes, with few exceptions such as eating disorders and severe psychiatric populations. Optimal doses of psychotherapy in routine settings range between 4 â 26 sessions (4 â 6 for low intensity guided self-help) and vary according to setting, clinical population and outcome measures. Weekly therapy appears to accelerate the rate of improvement compared to less frequent schedules. Most of the reviewed evidence is from university counselling centres and outpatient psychotherapy clinics for common mental health problems. There is scarce and inconclusive evidence in clinical samples with chronic and severe mental disorders

Comparison of face-to-face versus email guided self-help for binge eating: study protocol for a randomised controlled trial
Background
Guided self-help is a recommended first-step treatment for bulimia nervosa, binge eating disorder and atypical variants of these disorders. Further research is needed to compare guided self-help that is delivered face-to-face versus via email.
Methods/Design
This clinical trial uses a randomised, controlled design to investigate the effectiveness of providing guided self-help either face-to-face or via e-mail, also using a delayed treatment control condition. At least 17 individuals are required per group, giving a minimum N of 51.
Discussion
Symptom outcomes will be assessed and estimates of cost-effectiveness made. Results are proposed to be disseminated locally and internationally (through submission to conferences and peer-reviewed journals), and will hopefully inform local service provision. The trial has been approved by an ethics review board and was registered with ClinicalTrials.gov NCT01832792 on 9 April 2013
A pragmatic effectiveness study of 10-session cognitive behavioural therapy (CBT-T) for eating disorders: Targeting barriers to treatment provision
Objective
Tenâsession cognitive behavioural therapy (CBTâT) for transdiagnostic eating disorders targets several barriers to treatment, including cost, therapist expertise, and lengthy wait lists.
Method
We used a case series design to investigate the effectiveness of CBTâT delivered by trainee psychologists in a postgraduate training clinic. Participants were randomly allocated to commence treatment either immediately or after a 4âweek waitlist period. CBTâT was delivered to 52 patients, by six different trainees under supervision. Measures of eating disorder cognitions and behaviours, quality of life, and general psychopathology were examined in completer and intentionâtoâtreat analyses using multilevel modelling. Last observation carried forward was applied for abstinence, remission, and good outcome analyses to aid comparison with prior studies.
Results
Significant improvements, associated with medium to large effect sizes, were found for eating disorder cognitions, behaviours quality of life, and negative affect from baseline to posttreatment, and at 1â and 3âmonth followâup. Attrition (38.5%) was comparable with other treatment studies.
Conclusion
Results provide evidence for the effectiveness of CBTâT delivered by trainee psychologists for transdiagnostic eating disorder patients, thus tackling some important barriers for treatment. Longer followâup, randomised controlled trial designs, and moderator analyses will provide more robust evidence about which patients do best with a shorter therapy

rating scale to measure therapist adherence
in the Strong Without Anorexia
Nervosa (SWAN) study, a multi-center
randomized controlled trial comparing
three different psychological treatments
for adults with anorexia nervosa. The
three treatments under investigation
were Enhanced Cognitive Behavioural
Therapy (CBT-E), the Maudsley Anorexia
Nervosa Treatment for Adults (MANTRA),
and Specialist Supportive Clinical
Management (SSCM).
Method: The SWAN Psychotherapy Rating
Scale (SWAN-PRS) was developed, after
consultation with the developers of the
treatments, and refined. Using the SWANPRS,
two independent raters initially
rated 48 audiotapes of treatment sessions
to yield inter-rater reliability data. One
rater proceeded to rate a total of 98
audiotapes from 64 trial participants.
Results: The SWAN-PRS demonstrated
sound psychometric properties, and
was considered a reliable measure of
therapist adherence. The three treatments
were highly distinguishable by
independent raters, with therapists
demonstrating significantly more
behaviors consistent with the actual
allocated treatment compared to the
other two treatment modalities. There
were no significant site differences in
therapist adherence observed.
Discussion: The findings provide support
for the internal validity of the SWAN
study. The SWAN-PRS was deemed suitable
for use in other trials involving CBT-E,
MANTRA, or SSCM. VC 2015 The Authors.

Associations between body mass index, weight control concerns and behaviors, and eating disorder symptoms among non-clinical Chinese adolescents
<p>Abstract</p> <p>Background</p> <p>Previous research with adolescents has shown associations of body weight, weight control concerns and behaviors with eating disorder symptoms, but it is unclear whether these associations are direct or whether a mediating effect exists. This study was conducted to investigate the prevalence of overweight and obesity, weight control concerns and behaviors, and eating disorder symptoms and to examine the mediating function of weight control concerns and behaviors on the relationship between body mass index (BMI) and eating disorder symptoms among non-clinical adolescents in China.</p> <p>Methods</p> <p>A cross-sectional survey among 2019 adolescent girls and 1525 adolescent boys in the 7th, 8th, 10th and 11th grades from seven cities in China was conducted. Information on weight control concerns and behaviors, and eating disorder symptoms (Eating Disorder Inventory-3) were collected from the adolescents using a self-administrated questionnaire.</p> <p>Results</p> <p>Weight control concerns and behaviors, and eating disorder symptoms were prevalent among the study population. A high proportion of adolescents scored at or above the threshold on the eating disorder inventory (EDI) subscale such as bulimia, interoceptive deficits, perfectionism, and maturity fears, which indicated eating disorder symptoms. High BMI was significantly associated with high score of drive for thinness, body dissatisfaction, bulimia, low self-esteem, interceptive deficits and maturity fears, so do perceived body weight status. Almost all weight control concerns and behaviors we investigated were significantly associated with high EDI subscale scores. When weight control concerns were added to the model, as shown in the model, the association between BMI and tendency of drive to thinness and bulimia was attenuated but still kept significant. The association between BMI and body dissatisfaction were no further significant. The association of BMI and drive for thinness, body dissatisfaction and bulimia was considerably weaker than when weight control behaviors were not included.</p> <p>Conclusions</p> <p>Weight control concerns and behaviors may be mediators of the association between BMI and eating disorder symptoms. Interpretation of these weight control problems is crucial to develop culturally appropriate educational and intervention programs for adolescents.</p
Patient interpersonal factors and the therapeutic alliance in two treatments for bulimia nervosa
The lived experience of working with people with eating disorders: A meta-ethnography
Objective
Working with people with eating disorders (EDs) is known to elicit strong emotional reactions, and the therapeutic alliance has been shown to affect outcomes with this clinical population. As a consequence, it is important to understand healthcare professionals' (HCPs') experiences of working with this client group.
Method
A metaâsynthesis was conducted of qualitative research on HCPs' lived experiences of working with people with EDs. The results from the identified studies were analyzed using Noblit and Hare's metaâethnographic method. Data were synthesized using reciprocal translation, and a line of argument was developed.
Results
Thirtyâseven studies met the inclusion criteria. Reciprocal translation resulted in a key concept: âCoping with caring without curing.â This was underpinned by the following thirdâorder concepts: (a) âThe dissonance and discomfort of being a helper struggling to help,â (b) âDefending against the dissonance,â and (c) âAccepting the dissonance to provide safe and compassionate care.â These concepts were used to develop a lineâofâargument synthesis, which was expressed as a new model for understanding HCPs' experiences of working with people who have an ED.
Discussion
Although the conflict associated with being a helper struggling to help led some HCPs to avoid and blame people with EDs, others adopted a compassionate stance characterized by humanity, humility, balance, and awareness
Reliability of self-report of health in juvenile offenders
The aim of the present study was to investigate the accuracy of self-reports of juvenile offenders on physical factors (e.g., sleep difficulties, weight related behaviors and weight perceptions), health risk behaviors (e.g., alcohol use), trauma history (e.g., physical and sexual abuse) and psychological factors (e.g., anxiety, suicidal and self-harm behaviors). Self-reports obtained via a Health Questionnaire from 242 incarcerated juvenile offenders were compared with standardized measures (Body Mass Index, Adolescent Psychopathology Scale and Child Trauma Questionnaire) to investigate the reliability (via construct validity) and veracity of their self-report. Using kappa estimates and receiver operating characteristic curves, results generally showed high agreement across measures, suggesting that self-report questions from the health survey could all be used reliably. The degree of accuracy indicated that young offenders are as reliable as clinical and community samples of adolescents in their self-report. These findings have implications for routine assessments and practice evaluations that rely on self-report as the method of data collection and as the basis for clinical formulation and treatment planning
Protocol for the Foot in Juvenile Idiopathic Arthritis trial (FiJIA): a randomised controlled trial of an integrated foot care programme for foot problems in JIA
<b>Background</b>:
Foot and ankle problems are a common but relatively neglected manifestation of juvenile idiopathic arthritis. Studies of medical and non-medical interventions have shown that clinical outcome measures can be improved. However existing data has been drawn from small non-randomised clinical studies of single interventions that appear to under-represent the adult population suffering from juvenile idiopathic arthritis. To date, no evidence of combined therapies or integrated care for juvenile idiopathic arthritis patients with foot and ankle problems exists.
<b>Methods/design</b>:
An exploratory phase II non-pharmacological randomised controlled trial where patients including young children, adolescents and adults with juvenile idiopathic arthritis and associated foot/ankle problems will be randomised to receive integrated podiatric care via a new foot care programme, or to receive standard podiatry care. Sixty patients (30 in each arm) including children, adolescents and adults diagnosed with juvenile idiopathic arthritis who satisfy the inclusion and exclusion criteria will be recruited from 2 outpatient centres of paediatric and adult rheumatology respectively. Participants will be randomised by process of minimisation using the Minim software package. The primary outcome measure is the foot related impairment measured by the Juvenile Arthritis Disability Index questionnaire's impairment domain at 6 and 12 months, with secondary outcomes including disease activity score, foot deformity score, active/limited foot joint counts, spatio-temporal and plantar-pressure gait parameters, health related quality of life and semi-quantitative ultrasonography score for inflammatory foot lesions. The new foot care programme will comprise rapid assessment and investigation, targeted treatment, with detailed outcome assessment and follow-up at minimum intervals of 3 months. Data will be collected at baseline, 6 months and 12 months from baseline. Intention to treat data analysis will be conducted.
A full health economic evaluation will be conducted alongside the trial and will evaluate the cost effectiveness of the intervention. This will consider the cost per improvement in Juvenile Arthritis Disability Index, and cost per quality adjusted life year gained. In addition, a discrete choice experiment will elicit willingness to pay values and a cost benefit analysis will also be undertaken
Meaning in life is associated with the psychopathology of eating disorders: differences depending on the diagnosis.
Previous studies indicated that meaning in life was inversely associated with eating behaviors and a negative attitude toward food, body satisfaction, and borderline symptoms. However, research on the association between meaning in life and eating disorder psychopathology is scarce, and there are no studies on the association between meaning in life and the eating disorder psychopathology depending on the diagnosis. The aim of the present study is to verify whether meaning in life is differentially associated with a broad range of psychopathology symptoms commonly observed in people with ED, depending on the diagnosis, in a sample of 240 ED patients. We found that meaning in life was negatively associated with eating behaviors and a negative attitude toward food, body satisfaction, borderline symptoms, and hopelessness in all types of eating disorders, regardless of the specific diagnosis. Moreover, the association with meaning in life was different depending on the type of eating disorders. Specifically in the participants with Anorexia Nervosa Restrictive, meaning in life had a higher percentage of explained variance in the eating disorders psychopathology (between 30%-65%). Therefore, these results seem to indicate that, although meaning in life is an important variable in all the eating disorders subtypes, it is especially relevant in participants with the Anorexia Nervosa Restrictive subtype
